When your carbon monoxide alarm displays a number with no alarm
Any time a digital unit displays a number with or without an alert, assume it senses
carbon monoxide. Leave the home and call 911.
How to retrieve the error code on my carbon monoxide alarm
1. Push and hold the
Peak Level button. You will see an E and an O followed by a
number.
2. Contact product support at
1-800-880-6788 and provide us the error code,
along with the model number, assembly number and date of manufacture from
the back of your unit.
